Male elk bugling during the fall rut. Large male elk are known as bulls. Male elk have large antlers which are shed each year. Male elk engage in competitive mating behaviors during the rut, including posturing, antler wrestling and bugling, a loud series of screams which is intended to establish dominance over other males and attract females, Cervus canadensis, Mammoth Hot Springs, Yellowstone National Park, Wyoming

Mother and calf southern right whales are seen here as part of a larger courtship group, with adult males interested in mating with the mother. The calf has no choice but to stay by her mother's side during the courting activities, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Male and female southern right whales mating underwater, Eubalaena australis. The male positions himself below the female and turns upside down, so the two whales are belly-to-belly and can mate. Sand has been stirred up by the courtship activities and the water is turbid, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Courting pair of southern right whales underwater, Eubalaena australis. In this image, the male is below and inverted (belly up) and the female is at the surface. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating, Eubalaena australis, Puerto Piramides, Chubut, Argentina

White southern right whale calf underwater, Eubalaena australis. About five per cent of southern right whales are born white due to a condition known as grey morphism and will gradually turn dark as they age. They are not albino (which is a complete lack of pigmentation). Sometimes referred to as "brindled", the white coloration is a recessive genetic trait and only lasts a few months. Typically, but not always, white calves will become much darker as they mature but will still somewhat lighter than normal even as adults, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Rostrum and callosities of southern right whale, Eubalaena australis. Whale lice can be seen attached to the collosities, which are patches of thickened keratinized tissue, like calluses (thus the name). The pattern of callosities on a right whale are unique and serve as a way to identify individuals throughout their lifetime, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Courting pair of southern right whales underwater, Eubalaena australis. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating. The male is below, upside down and trying to access the female belly-to-belly. However, the female does not want to mate, so she has positioned herself upside down at the surface so that the males in the courting group cannot reach her genital slit, Eubalaena australis, Puerto Piramides, Chubut, Argentina
